@GraceGarwood For the first bullet point of your post, to have an email go to a different person based on the subject selected by the user you should use a Switch which is a type of condition that looks at just 1 thing, in this case the subject. There can be up to 25 "cases" for each Switch, i.e in case Subject equals Maths then do something, or in case Subject equals Chemistry the do something. Inside each switch you would have a set variable that saves the email address to send the email to. Then add a new send an email action action below the cases and for the To field select the variable.
A simple example of a Switch like this is shown below:
